In a double displacement reaction, which of the following pairs will react? (2021)
Step 1: Understand what a double displacement reaction is. It is a type of chemical reaction where two compounds exchange ions or bonds to form two new compounds.
Step 2: Identify the pairs of compounds given in the question. Each pair should consist of two ionic compounds.
Step 3: Check if the compounds in each pair can exchange ions. This usually happens if one of the products is a precipitate, a gas, or water.
Step 4: Confirm that all the given pairs can undergo this exchange and form new compounds.
Step 5: Conclude that since all pairs can react, they all can undergo double displacement reactions.
